Be it lmown that l, Fenix DE Bonseniiyn,

a citizen 'of the UnitedStateaiesidingat y l is-illustrated asadaptable for attachment to `vehicle cha'ssisjof existing types but it is to be' understood that the inv'entionf-may beembodied lin the chassis during the construction Chicagointhe county of Cook and State' of Qlllinois, have'invented new' and useful Imrovements inVehicle Chassis, of which the following is a specification, This invention* ,relates to motor vehicles or automobiles andan object ofthe inven` tion is to provide a vehicley vchassis embodying a novelfform y,of suspension,andfspring action for increasingthe shock absorbing `proclivities vof the chassis, and consequently increasetheeaseand smoothness of riding'of the vehicle. g .T Y. ,l of this inventiony is to provide, in the vehicletzchassisv anovel formof spring `bumper structure `and .suspension leinthe following detailed descriptionrtaken,

l vehicle chassis constructed'v in accordance y I v gage .upon opposite sides lof the. spring `versffwhich vcarry the axles ofthevehicle and are arranged whereby the shocks occasioned -by the travel of the vehicle over roughsur- `-faces or -undulations in the roadway,l to be transmitted 'totand absorbed by the kbuffer structures ina directiony substantially parallel withN the line of :travel of ythe vehicle thereby ypreventing vertical vibration of the vehicle body and :relieving `the -persons or contents of the vehicle body of thek joltsor shocks caused by theordinary type of spring suspension of vehicles. -1 y 'l Another objectof the'invention is to lprovide a vehicle chassiswliich will impart lthe desirable easy riding features of long wheel base cars or vehicles to short Wheel base vehicles permitting the ease'. of operation'of a short wheel base yvehicle -and the easy Vfeatures of a long wheel base. f 1

Other objects of the invention willfapp'earin connection with thefaccompanyingfdrawings wherein:

Fig. 11s a fragmentary top planoffthe on the line A14-4 of Fig.'1. 1

Fig. 5`is' a fraginentar y"seetion*taken on the line 5 5 of Figflffv L" riding i .l igifG is a detail section lviewy taken on` the In fthe? drawings, my improved y'invention thereof.l

. The drawings illustratel axle side,v bars y1 y?. and 2 vvlnch are adapted in any1 suitable manner; to the 'side` rails 3 of` the .vehicle chassis but in originally 'constructing Athe chassis the barsl r`and 2jwillbey eliminated and-the rails?) elongatedto provide the necv ,essaryf length, j 'y I The .axles .4 of the chassisyonlypone which is shovvnf .in the drawings aresupported-,by a plurality of pivotally mounted 7 to an axle engaging .neath the, chassis byfsuitable brackets 112.`

means 13 and they `have rearly extending fears 141;,formedthereonv to which rods are connected. jTherods k5 and G-are preferably `formed of I .beams which -,increase their y ystrength and the ends of the rods -6 remotev fromfthe axle 4 are connected'to thedependy carriedby collars lrwliich are rotatably -mounted upon an auxiliaryr axle 17*` support- 5 ed bythe bars 1 and'2. The depending arms lha've forwardly extending ho'rizontaleyL tensions 18 lformed thereon to whiclrforked members 19 are connected as shown at 20. The 'arms 21 'of the forkedrmcmbers 19 ensteel have ltheirends attached to the 4bars l and Qasindicated atQ; Thebars 22 and QSjare synchronously curved as at 25 'intermediate their straight portions 2G and `,their points ofI attachment tothe barsk 1 and 2 yto provide',` resilient shock Vabsorbing ing .arms l5. yThevdepending armsl are 1.05 springs for absorbing shocks incident with r the travel of the Wheels 27 over rough places in the roadway and prevent the transmission of the shock to the vehicle bodyk caiI4 ried by the chassis. i

lltivill be noted that owing yto the particular mounting of the rods 5 and 6. arms land their connection with thesprings 22 and 23 that the shocks will lbe delivered to the springs in a line substantially parallel with the line of travel of the vehicle preventing vibratory niovein'entof the bed or` body supported by the chassis and consequently greatly facilitating the smooth and easy riding of the vehicle. Spiral spr-ings 28 are connected to the straightportions of V the springs and'23 -andhave their ends lreinote from the springs 22and 23y seated in cups 29 carried byv suitable attaching brackets 30 which are clamped upon the auxiliary axle 17. The springs 2S co-oper- 'ate' with the synchronously 'curved Aportions x A bumper or butler spring' 31 is provided the ends of which are attached to the vbars 1 and 2 and the said bumper springs extend outwardly aboutthe synchronously curved portions 25 and parallel to the straight portions -26 ofthe springs 22 and 23 in spaced relation thereto. The spring' 31 serves the function of ythe usual bumper or lbuer spring on a inotorve-hicle and also Will cooperate with the springs 22 and 23 in absorbing shocks deliyered to the Wheels 27 When the springs 22 and 23 are forcedinto engagement with the spring 31. f

l/Vhen the device is attached to vehicles `of existing construction the bars-1 and 2 may be utilized forsiipporting platforms 32 which in turn may serve as luggage carriers. Standards 33 are shown attached to the "platforms 32 and these standards are vprovided for receiving straps or binders `for binding vluggage on the platforms lt u L Y n is to beunderstood that the improved floating suspension ofthe axle and shocky absorbing structures `may be utilized upon they vehicle chassis in connection with the elliptical or seiiiieelliptical springs, Without departing from the spirit of this invention.

lt is, of course,-to be understood that the "invention may be constructed in other man# ners andthe parts associated'iii other relations and, therefore, l donot desire to be limited in 'any other manner except asset forth in the clainishereunto appended. f

Having thus describediny inventionwhat l claim is: y

1. lua motor vehicle structure, the comb'ination With a vehicle'chassis, of a pair `provide sinuous convolutions intermediate vthe straight 4abutting portions and their points of attachment to the chassis, an axle on the vehicle, links pivotally connected to said axle, and an'articiilated connection be* tween said linlrs and the vabutting portions of said spring bars. y

2. ln a inotor vehicle structure. the combination with a vehicle chassis, of a pair of spring buffer bars connected to the front .end-of the chassis and having parallel engaging straight portions extending across the front of the chassis, said bars bentto provide sinuous conyolutioiis intermediate the straight abiitting 'portions and their points of attachment to the chassis, an axle onthe Vehicle, linlrs pivotally connected to said axle,4 an articulatedconnection between saidlinlrs and the abutting portions 'of said spring bars, :and a spring bumper attached to the chassis and extending rvabout said spring bars across the "front of the chassis in parallel spacedrelation to the abutting 4portions with the spring bars.

.axle on the vehicle, links pivotally connected to said axle.` an'farticulated connection between said links and the abutting portions of said spring bars, a cross yrod carried by the chassis rearwardly 'of said axle., and links pivotally connected tothe axle and' to said cross rods.
